 |`--enable-heapdump`|false|Enables NodeJS memory dumps collection feature. This feature is extremely useful for finding memory leaks. Use the 'kill -SIGUSR2 <PID>' command to create a dump of memory heap for _node_ process with the particular PID (this works for *nix systems only). The dump file will be created in the same folder, where main Appium script was executed and will have *.heapsnapshot extension. These snapshot can be then loaded to Chrome Inspector for further investigation. Read the [Rising Stack article](https://blog.risingstack.com/finding-a-memory-leak-in-node-js/) for more details.||
